I personally feel it is the duty of every honest person. To play with these scammers when we have the chance.
I once had a guy try to rip me off when selling a car. He said he would pay $7.000 via Paypal, but nothing came into my account. Instead, I received an email from paypalsupport@gmail.com :) telling me I just received a payment.
The guy overpaid by $2k so he wanted me to Western Union the rest to him.
I played the fool perfectly. Promised him I would go to Walmart and send the transfer later in the day. I them called him a few hours after, claiming the line at Walmart was too long. He tried his best to convince me to wait it out, but I told him I had other things to do and would send the money the next day.
Long story short I bs'ed him for a couple of days before the idiot figured I was messing with him.
It was awesome. I could hear how happy he was when I said I was going to send the money. He thought he had found a sucker LOL.
I take great pleasure knowing I gave the jerk false hope, only to break his soul.
This was my first time and I was curious how he will develop his storry :)
